A closed tank 2m high and 1m in diameter contains 1.5 m water. The air in the space above water is subjected to a pressure of 117.72 kN/m². If the tank is rotated at an angular velocity of 12.0 rad/s, what are the pressure intensities at the centre of the bottom and near the walls at the bottom of the tank? Also find the speed at which this tank should be rotated in order that the centre of the bottom has zero depth of water.
